Dual- Lok Hub Mount 1.375x24

What makes this mounting system unique?  It is a combination of desirable mechanical features and performance characteristics in a lightweight, compact system.  DUAL-LOK™ combines a precision, sealing, and alignment taper interface with a stub ACME thread, and provides ease of secure attachment. A robust wave spring provides a reliable and positive heat-resistant spring action to the redundant locking collar (second locking feature).  The locking collar is semi permanently installed to the mount via factory press slpined, stainless steel, taper pins.  Since the mount has no wear prone metal on metal sliding actions like many other mounts, there is no need for the operator to disassemble the system.  This locking ring includes three anti-rotation splines which ensure the suppressor will not come off inadvertently.  The muzzle device integrates 60 machined mounting position grooves which is doubled by the mount’s two locking positions, hence the double entendre DUAL-LOK™. How is this achieved? The mounts’ two locking positions are machined out of phase of one another by 3 degrees which provides the 120 effective locking positions and ensures a tightly mounted and locked suppressor.  When the suppressor is installed only one of the two positions will generally function by allowing the spring to push the locking collar rearward over the splines. 

Substantial efforts are taken in the manufacturing and inspection of the DUAL-LOK™ products to ensure Griffin customers are outfitted with the best QD mounting systems available.
